使用yum安装CDH5

环境

三台天翼云主机 （node209, node452, node440）

OS：CentOS 6.5 64位

JDK：Oracle JDK 1.7.0_45

安装ZooKeeper（集群模式）

Node Type:

node229, node452, node440

 

1.所有节点安装zookeeper, zookeeper-server

yum install -y zookeeper zookeeper-server

 

2.所有节点修改zookeeper配置文件

vi /etc/zookeeper/conf/zoo.cfg

增加节点的配置

server.1=node229:2888:3888
server.2=node452:2888:3888
server.3=node440:2888:3888

 

3.所有节点初始化zookeeper-server

每个节点的myid唯一

node229:service zookeeper-server init --myid=1

node452:service zookeeper-server init --myid=2

node440:service zookeeper-server init --myid=3

 

4.所有节点启动zookeeper

service zookeeper-server start

 

5.查看zookeeper状态

zookeeper-server status

 

安装CDH（集群模式，HDFS+YARN）

Node Type:

namenode: node229

datanode: node229, node452, node440

yarn-resourcemanager: node452

yarn-nodemanager: node229, node452, node440

mapreduce-historyserver: node440

yarn-proxyserver: node440

 

node1: 

yum install hadoop-hdfs-namenode

node2: 

yum install hadoop-yarn-resourcemanager

node3: 

yum install hadoop-mapreduce-historyserver hadoop-yarn-proxyserver

所有节点:

yum install hadoop-client

yum install hadoop-yarn-nodemanager hadoop-hdfs-datanode hadoop-mapreduce

 

部署CDH

1.部署HDFS

(1) 配置文件

core-site.xml

  <property>
    <name>fs.defaultFS</name>
    <value>hdfs://node229:8020</value>
  </property>

 

  <property>
    <name>fs.trash.interval</name>
    <value>1440</value>
  </property>

 

hdfs-site.xml

  <property>
    <name>dfs.permissions.superusergroup</name>
    <value>hadoop</value>
  </property>

 

  <property>
    <name>dfs.namenode.name.dir</name>
    <value>/hadoop/hdfs/namenode</value>
  </property>

 

  <property>
    <name>dfs.datanode.data.dir</name>
    <value>/hadoop/hdfs/datanode</value>
  </property>

 

  <property>
    <name>dfs.webhdfs.enabled</name>
    <value>true</value>
  </property>

 

slaves

node209

node452

node440

 

(2)创建namenode和datanode文件夹

namenode:

mkdir -p /hadoop/hdfs/namenode
chown -R hdfs:hdfs /hadoop/hdfs/namenode
chmod 700 /hadoop/hdfs/namenode

datanode:
mkdir -p /hadoop/hdfs/datanode
chown -R hdfs:hdfs /hadoop/hdfs/datanode
chmod 700 /hadoop/hdfs/datanode

 

(3)格式化namenode

sudo -u hdfs hadoop namenode -format

 

(4)启动hdfs

namenode(node209):

service hadoop-hdfs-namenode start

datanode(node209, node452, node440):

service hadoop-hdfs-datanode start

(for x in `cd /etc/init.d ; ls hadoop-hdfs-*` ; do sudo service $x start ; done)

 

(5)查看hdfs状态

sudo -u hdfs hdfs dfsadmin -report

sudo -u hdfs hadoop fs -ls -R -h /

 

(6)创建HDFS临时文件夹

sudo -u hdfs hadoop fs -mkdir /tmp

sudo -u hdfs hadoop fs -chmod -R 1777 /tmp
